What do the numbers in Wei Zi's chart represent?

I want to know, what do the numbers in each grid in Wei Zi's chart stand for?

The number in each grid in the chart is the age of the host and also represents an age range. For example, the number in one cell is 6- 15, which means 6- 15 years old. The ten-year deadline is called the deadline in Weizimen, so it is also called the deadline 6- 15.

Does it represent the corresponding age?

It represents the corresponding age, pay attention to the nominal age.
